Gold ring with purple gemstone and inscription inside

I lost my gold ring with a small purple gemstone yesterday around 4pm near the Brunswick Town Hall on Park Street. It's a 14k yellow gold band, about 6mm wide, with a lavender center stone and a delicate engraving on the inner side that reads 'A.K.' The ring is slightly worn, with a couple of faint scratches and a tiny bend in the band. It was a gift from my grandmother and means a lot to me, so I’m really hoping to get it back.
